Camouflage Using Surface Disruption: The Importance of Corners Versus Edges

Ecology and Evolution
Disruptive colouration is a common mode of camouflage used by predators and prey to conceal their body contours. However, it is unclear how disruptive colouration hinders the detection and recognition of three‐dimensional (3D) body shapes.

Scorpionfish rapidly change colour in response to their background

Frontiers in Zoology, 2023
Background To facilitate background matching in heterogenous environments, some animals rapidly change body colouration. Marine predatory fishes might use this ability to hide from predators and prey. Here, we focus on scorpionfishes (Scorpaenidae), well-

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Chromatic Contrast Alone Does Not Predict Predation Risk in the Longhorn Beetle Rosalia alpina

Ecology and Evolution
Colouration can affect predation risk through camouflage, signalling, or other mechanisms that shape predator perception and decision‐making. The Rosalia longicorn (Rosalia alpina), a flagship longhorn beetle of European beech forests, has a bluish‐grey ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

The Geographical Variation of Colour Change in the Arabian Killifish (Aphaniops dispar Sensu Lato) From Freshwater and Marine Ecosystems

Ecology and Evolution
Widely distributed animals may exhibit substantial plastic physiological, morphological and behavioural responses to environmental changes. One such extraordinary form of plasticity is colour change, which varies substantially among most taxonomic groups.

Dynamic colour change in zebrafish (Danio rerio) across multiple contexts

Royal Society Open Science
Many animals are capable of rapid dynamic colour change, which is particularly well represented in fishes. The proximate mechanisms of dynamic colour change in fishes are well understood; however, less attention has been given to understanding its ...

Matching of Remote Sensing Images with Complex Background Variations via Siamese Convolutional Neural Network

Remote Sensing, 2018
Feature-based matching methods have been widely used in remote sensing image matching given their capability to achieve excellent performance despite image geometric and radiometric distortions.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
